WORLD FORMULA ENGINES
OIL
Oil is the lifeline of any engine and using good quality oil is a must! We recommend running 16 ounces of a kart spe-
cic racing oil. We no longer recommend using automotive oil beyond break-in due to recent domestic and international
changes that could adversely affect product life. It is important that oil is changed and monitored on a regular basis as
dirt and other contaminants such as fuel, etc. will impact the life of this engine.
NOTE: For your engine break-in period use ONLY a high grade SAE-rated non-synthetic 30 weight oil. Use of synthetic oil
during this process could prevent proper “seating” of the piston rings, etc.
ENGINE BREAK-IN (RUNNING IN)
The rst 30 minutes of this engine’s life are the most important to ensure trouble-free racing. After mounting to the kart,
we recommend that the engine be broken in using any high grade non-synthetic SAE-rated 30 weight oil. Run the engine,
no load, at idle (1,700-2,000 rpm) to allow the engine to reach normal operating temperature (5-8 minutes). Shut the
engine off and allow to return to room temperature.
Again start up the engine and bring up to temperature (5-8 minutes). Shut off engine and change the oil. Replace the oil
(16-18 ounces) and it is time to place ‘load’ on the engine. To apply a load on the engine the easiest way to do this is to
run the engine on the track. Running not higher than 6,000 rpm, take several laps (depending on course length). With
the oil still warm drain and replace the oil. Repeat and slowly begin to bring the engine up to speed.
FUEL
This engine was designed for 98 Octane (RON) or 93 Octane (RON+MON/2) pump gas. The use of lower octane fuels
could cause engine detonation and/or adversely affect your engine’s life.
MAXIMUM RECOMMENDED RPM
Your engine has been equipped with a governor system that will limit the RPM of this engine to around 7,100 RPM + 50
RPM. This does not take away from the need to have a return to idle mechanism. Removal or tampering of this system
could lead to reduced engine life, and/or serious injury, possibly even death. Also, we do not recommend repetitive use of
the rev limiter as a limiting factor of RPM. This rev limiter works by actively ‘shorting’ the ignition system of your engine.
In repetitive situations fuel loading as well as increased internal stress load of the engine can occur, greatly reducing
engine life.

Do not disconnect or modify the installed rev limiter. Engine overspeeding can result in ywheel
failure or part failure, causing death, serious injury or property damage.
